Image Array Collision Detection

Hey, all! I'm trying to figure out how to add collision detection to the following code but I'm having trouble trying to figure out how to pull in the x and y coordinates of the different eggs that are falling randomly. Would you be able to tell me what I'm doing wrong? Thank you!

I've not used this plugin but assume that its "accurate collision-testing of turtles with arbitrary convex hulls" can be used for collision detection of turtles with each other, ie. turtlize each of your eggs.

You would need to more-or-less restart your coding from scratch but would benefit from many hours of good work put in by the plugin's author.
